Bariatric surgery is an effective treatment for children and adolescents with severe obesity. However, outcomes in youth with cognitive impairments and/or developmental delays are understudied. This paper reviewed the literature on bariatric surgery within this population. Fourteen studies published from 1975 to 2019 were identified. The majority (93%) of studies included patients with genetic disorders. Most studies reported no peri-operative complications (69%) and improved health outcomes (79%), with variable weight-loss results (29.2-86.2% excess weight loss). No significant differences were reported for youth with and without cognitive impairment and/or developmental delay in two studies. Limited available data suggest bariatric surgery may promote weight loss and improve health comorbidities for youth, irrespective of cognitive or developmental functioning. Clinical recommendations for working with patients and families are included.
